RESP Age Limits: Contribution Rules, Grant Eligibility and Deadlines

A parent who opens a Registered Education Savings Plan (RESP) for the first time when their child is 16 usually assumes they’ve still got two years before anything runs out. In one sense that’s true. In the sense that actually matters for free government money, it can already be too late, because qualifying for the Canada Education Savings Grant (CESG) at 16 or 17 depends on contribution history that has to exist before the child turns 15. Miss that window and no amount of catching up in year 16 fixes it.

That single trap is a good reason to lay out every age-based deadline built into an RESP in one place, in the order a child actually moves through them, rather than scattered across a dozen separate rules that only make sense once you already know they exist. It’s a companion piece to the broader rundown of RESP government grants, focused specifically on when each one opens and closes rather than what each one pays.

Birth to Age 5: No Deadlines Yet, But the Clock Is Running

Nothing forces you to open an RESP the day a child is born, and there’s no penalty for waiting a year or two. What you lose by waiting is compounding room, not eligibility. The CESG matches 20 percent of contributions up to $500 a year, with a $7,200 lifetime cap per child, and every year without a contribution is a year of matching that can only be partially recovered later, since the catch-up rate is capped at $1,000 in CESG per year even when multiple years are owed. There’s no downside to opening the account early and contributing modestly rather than waiting for a “better” time that never quite arrives.

Ages 6 to 9: British Columbia’s Narrow Window

Families in British Columbia get one grant with an actual expiry built around a specific age band rather than a running total. The British Columbia Training and Education Savings Grant pays a one-time $1,200 into an eligible child’s RESP, and the application has to be submitted sometime between the child’s sixth birthday and the day before their ninth. Miss the window entirely and the $1,200 is simply gone. No other RESP grant in Canada is boxed in by both a start date and an end date this tightly, which makes it the easiest one to lose track of if a family opens the account later than expected or assumes, incorrectly, that it works like the CESG and stays available indefinitely.

Age 15: The Quiet Cutoff for the Canada Learning Bond

The Canada Learning Bond, aimed at lower-income families and requiring no contribution at all, pays its last regular instalment in the calendar year a beneficiary turns 15. After that, no further annual amounts get added, even though the government will still let a family apply retroactively for years already missed, right up until the day before the beneficiary’s 18th birthday. Past that point, the young adult can apply for the bond themselves between ages 18 and 20, with the actual cutoff falling the day before their 21st birthday. This retroactive window is genuinely generous, and a family that never knew they qualified in earlier years isn’t necessarily out of luck, but the deadline for adding new eligible years still lands quietly at 15, well before most parents are thinking about RESP deadlines at all.

Ages 16 and 17: The Rule That Catches Late Starters

This is the one worth reading twice if a family is opening an RESP for an older child. The Canada Education Savings Grant is available on contributions made up to the end of the calendar year a beneficiary turns 17, which sounds like plenty of runway. But a beneficiary who is 16 or 17 only qualifies for that grant if at least one of two conditions was already met before the end of the year they turned 15. Either a minimum of $2,000 was contributed to the RESP by then, or at least $100 was contributed in each of four separate years before then. A family that opens an account for the first time when their child is 16 has already missed both paths, and no lump sum contributed in year 16 or 17 changes that. The CESG simply isn’t available to that beneficiary going forward, full stop.

This is worth planning around specifically if there’s any chance of opening an RESP later in a child’s life, whether due to immigration timing, a change in family circumstances, or simply not knowing the account existed sooner. Reading up on the contribution catch-up rules that apply in ordinary years is useful, but they don’t rescue this particular situation, since the 16-and-17 requirement is a separate, earlier-triggering condition rather than a version of the standard catch-up mechanic.

Turning 18: Less Changes Than People Expect

Eighteen feels like it should be a major RESP milestone, and mostly it isn’t. The CESG has already stopped by this point, since eligibility ends the year the beneficiary turned 17. The BCTESG window is long closed for most families by 18 as well. What actually opens up around this age is the ability to receive Educational Assistance Payments once enrolled in a qualifying or specified program, assuming enrollment happens around the usual post-secondary timeline, and the Canada Learning Bond self-application window for young adults who weren’t signed up earlier. Otherwise, an RESP that’s already funded keeps operating on the same account-level rules regardless of the beneficiary crossing 18. There’s no reset, no new limit, and no fresh grant unlocking at this age.

Age 21: The Line That Matters Most for Family Plans

Twenty-one shows up in more RESP rules than any other single age, and it applies differently depending on plan type. A beneficiary added to a family RESP has to be under 21 at the time they’re named, with one exception for a beneficiary transferring in from another family plan where they were already named. Individual plans carry no such restriction at all, and can even be opened for an adult, including yourself. Age 21 also governs whether a sibling can be swapped in as a replacement beneficiary without triggering a repayment of CESG already paid into the account. Swap in a sibling under 21 and the grants stay put. Swap in anyone 21 or older, sibling or not, and the CESG tied to that money has to go back to the government.

The same age resurfaces again at the far end of a plan’s life, as one of the conditions that has to be met before the leftover investment growth can be paid out as an Accumulated Income Payment. If a beneficiary never pursues further education, that growth eventually becomes accessible once every beneficiary who’s ever been part of the plan has turned 21 and is no longer eligible for an EAP, alongside the plan itself having existed past a specific anniversary.

Age 31: The Contribution Cutoff

Contribution rules split by plan type here as well. For a family plan, contributions can only be made on behalf of a beneficiary who is under 31 years of age at the time the contribution happens, full stop, regardless of when the plan itself was opened. Individual, non-family plans work differently and aren’t tied to the beneficiary’s age in the same way, instead running on a window measured from when the plan was opened, which typically extends 31 years from that date before new contributions stop being accepted at all. Either way, nobody is topping up an RESP indefinitely. There’s a real end date to adding new money, well before the plan itself has to close.

Year 35 (or 40): When the Plan Itself Has to Close

Every RESP has an outer boundary on how long it can exist as a plan, separate from whether anyone’s still contributing or withdrawing from it. An ordinary plan has to be terminated by the end of the year that includes its 35th anniversary. A specified plan, meaning one set up for a beneficiary who qualifies for the disability tax credit, gets extended to the 40th anniversary instead. These same numbers double as conditions under which an Accumulated Income Payment becomes available if a family hasn’t already dealt with the account some other way by then. A plan sitting dormant for decades because nobody got around to closing it isn’t really an option. The calendar eventually forces the decision.

Age 59: The Outer Edge for an RDSP Rollover

There’s one more age limit that only matters for a specific group of families, and it’s easy to miss entirely because it lives in RDSP rules rather than RESP ones. If RESP growth is being rolled over tax-deferred into a Registered Disability Savings Plan (RDSP) for a beneficiary who qualifies for the disability tax credit, that rollover isn’t available once the beneficiary is over 59 in the year it happens. Given that RDSP age limits already shape how long that account itself can accept money, this cutoff is really the point where two separate accounts’ age rules intersect, and it’s worth knowing about well before a family gets anywhere close to it, since it’s not the kind of deadline anyone thinks to check for in advance.

Building Your Own Timeline

Write down your own child’s actual birth year against every deadline above rather than treating these as abstract rules. If you’re in British Columbia, mark the calendar for the sixth birthday specifically, since that grant application window won’t wait. If a beneficiary is already 14 or 15 and the RESP isn’t open yet, check whether the $2,000 or four-years-of-$100 condition can still be met before the end of the year they turn 15, since that decision alone determines whether the CESG is available at all going forward. And if you’re weighing a family plan against an individual one, let the age-21 naming rule inform that choice now, rather than discovering it later when a sibling situation makes it relevant.
